If you are receiving your final loadsheet in the lane with LMC's needed to be made to the FMC
Bergie, if you are going to make criticisms of the system, I think you should understand it first. None of what you say takes place. All figures are worked out for a provisional loadsheet and entered into the system pre-pushback, and all take-off calculations made. On taxi, when you receive the final figures by ACARs, 19 times out of 20 you are within parameters and do nothing but acknowledge and take-off. Just occasionally you have to enter higher weights, which is done in seconds. Considering BA has never had such a data entry error that you accuse them of risking, I think the system is perfectly safe- safer than several other airlines appear to use.
Perhaps it's time for South Africa to include the UK "advise when FULLY ready" phrase before calling for pushback??
Another daft posting! YOU are not 100% ready on pushback either. YOU have checks to carry out and cabin briefings to complete too. A 747 takes time. NOBODY is 'fully ready' on pushback! Throwing tantrums about it is pathetic- like getting upset when somebody enters the runway, then can't take off because of a fault!
